If you wish to utilize the analyzer's status outputs to interface with a device that accepts
logic-level digital inputs, such as programmable logic controller (PLC) chips, you can access
them through a 12 pin connector on the analyzer's rear panel labeled STATUS.

ON if no faults are present.
ON if concentration measurement (NO, NO2 or NOx) is valid.
OFF any time the hold-off feature is active.
ON if unit is in high range of the Auto Range Mode.
ON whenever the instrument is in ZERO point calibration mode.
ON whenever the instrument is in SPAN point calibration mode.
ON whenever the instrument is in diagnostic mode.
The emitters of the transistors on pins 1-8 are tied together.
